Description

Sodium Hexametaphosphate CAS NO 10124-56-8 is a versatile inorganic polyphosphate salt widely recognized for its exceptional sequestering, dispersing, and water-softening properties. This compound is critical for industrial processes where controlling water hardness and preventing scale formation is paramount. It serves as a key functional ingredient for manufacturers in the water treatment, food processing, detergent, and ceramics industries, ensuring product stability and process efficiency.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor in industrial cooling and boiler water systems.
• Food Industry: Used as a sequestrant, texturizer, and emulsifying salt in processed meats, seafood, dairy products, and beverages (often as Food Grade SHMP).
• Detergent & Cleaning Formulations: Functions as a builder to enhance cleaning power by softening water and preventing redeposition of dirt.
• Ceramics & Drilling Fluids: Serves as an efficient dispersing agent for clays and other minerals.
• Metal Treatment & Painting: Used in surface treatment processes for degreasing, derusting, and as a component in paint formulations to prevent pigment settling.
• Paper & Textile Manufacturing: Acts as a dispersant for pigments and aids in the bleaching process.

Quality Control

Our Sodium Hexametaphosphate is manufactured under a stringent quality management system. We offer various grades, including Technical, Food (FCC), and high-purity grades, each produced to meet specific industry requirements. Every batch is tested against rigorous specifications for parameters such as assay, phosphate content, and insoluble matter. Certificates of Analysis (COA) are provided to ensure traceability and compliance with relevant standards such as FCC, FAO/WHO, or customer-specific protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. This product is hygroscopic (moisture-sensitive) and must be kept in original packaging or a suitable moisture-proof container to prevent caking and degradation. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
